CHURN.

SPECIFICATION forming part of Letters Patent No. 697,970, dated January25, 1898.

Application filed June 10,1897. Serial No.640,196. (No model.)

To all whom it may concern.-

Be it known that I, NEWTON. E. FERRELL, acitizen of the United States,residing at West Finley, in the county of Washington and State ofPennsylvania, have invented new and useful Improvements in Ohnrns, ofwhich the following is a specification.

This invention relates ,to churns of that class in which the dasher isto have a vertical reciprocation and also an oscillatory or rotarymovement, first in one direction and then in the other, thus impartingfour motions to the dasher, or a right-and-left and up-and-down movementin spiral circles.

In the annexed drawings, Figure 1 is a sectional elevation of myimproved churn. Fig. 2 is a partly-sectional view of the socketed andspirally-grooved dasher-shaft. Fig. 3 is a plan of a two-part collar tobe loosely mounted on the dasher-shaft and provided with an arm forattachment of a pit-man to reciprocate the dasher in averticaldirection. Fig. 4 is a perspective of the churn-dasher.

The churn body 1 may be of any suitable or usual form, preferablycylindrical. There is mounted on the churn-body a verticallyextendedframe 2, that supports at its upper part a nut or hearing 3, the bore ofwhich is,

spirally ribbed to engage with the spiral grooves 4 of a dasher-shaft 5,Figs. 1 and 2. This dasher-shaft 5 is shouldered or provided with acircumferential groove 6, Fig. 2, in which is mounted a loose collar 7,Fig. 3, that is preferably formed in two parts united by bolts 8 tofacilitate fitting the said collar onto or around'the shaft.

From one side of the loosely-mounted collar 7 there projects a bearing 9for attachment of the upper end of a pitman 10, the lower end of whichconnects with a wrist-pin 11 on a gear-wheel 12, that is mounted in thelower part of the churn-frame. A crank handle 13, connected with thegear-wheel 12, affords means for rotating said wheel to impart verticalmovement to the dasher-rod 5 through the intermediate pitman. In itsvertical movement the dasher-rod 5 has also imparted to it a rotary oroscillatory motion, first in one direction and then the other, throughthe spirally-grooved connection of the said shaft with the nut orhearing 3,

through which the shaft is passed. The loose collar 7 permits therequired oscillatory or rotary movement of the dasher-shaft 5simultaneously with its vertical reciprocation.

A out or a slip-collar 14is provided on the end of the bearing 9 to holdthe end of the pitsocket 17 to receive the staff 18 of the dasher 19,and a set-screw 20 or other suitable fastening is provided fordetachable connection of the said shaft and dasher-stafi.

The dasher 19, Fig. 4, comprises crossed bars 21, secured to the lowerend of the staff 18 in a horizontal direction and at right allgles toeach other, and also-similar crossed bars 22, secured to the stafi atabout eight inches, more or less, from its lower end. These lowercrossed bars 21 and upper crossed bars 22 afford attachment fordiagonally arranged spindles 23 and 24, that are inclined in oppositedirections, as shown, one pair of spindles, 23, being extended, forinstance, from the inner or central portion of one lower cross-bar 21 tothe outer ends of the correspondin g upper cross-bar 22,and the otherpair of spindles, 24, being extended from the outer ends of the otherlower cross-bar to the central portion of the corresponding uppercrossbar. It will be seen that with the means for imparting to thisdasher a vertical reciprocation or up-and-down movement and anoscillation first to the right and then to the left each inclinedspindle 23 and 24 will cut a different spiral circle in the milk, sothat with the four motions given to the dasher the milk is thoroughlyand rapidly agitated in a great variety of directions and the butter isquickly separated. The churn is very easily operated and does its workspeedily and eifectively, making it possible to churn the milk at a lowtemperature and preserve the natural color of the butter.

What I claim as my invention is-- In a churn, the combination of theaxially-oscillatory and vertically-reciprocating dashenshaft having anannular groove intermediate the shaft ends and provided with a spiralgroove throughout the upper portion of the shaft, aframe provided at thetop with a, fixed nut having a spirally-ribbed bore engaging the spiralgroove of said shaft to im- 5 part oscillation thereto on up-and-downmovement of the shaft, a collar loosely mounted in said annular grooveof the dasher-shaft, a.

- pitman connected to said loose collar, gearing for driving the pitman,and a. dasher detachably connected with said shaft, substan- 1o tiallyas described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
